Exhibit 10.1

EXCHANGE AND SETTLEMENT AGREEMENT

     EXCHANGE AND SETTLEMENT AGREEMENT, dated December 27, 2007 (this “Agreement”), is among LCC International, Inc., a Delaware corporation (the “Company”), and the Investors listed on the signature pages hereto (collectively, the “Investors”).

W I T N E S S E T H:

     WHEREAS, the Company entered into a Purchase Agreement, dated as of April 19, 2007 (the “Purchase Agreement”), with the Investors party thereto pursuant to which, among other things, the Company issued an aggregate of 5.1 million shares (the “Old Shares”) of the Company’s Class A Common Stock, par value $0.01 per share (the “Common Stock”); and

     WHEREAS, in connection with the Purchase Agreement, the Company entered into a Registration Rights Agreement, dated as of April 19, 2007 (the “Registration Rights Agreement”), pursuant to which, among other things, the Company agreed to register the Old Shares with the Securities and Exchange Commission (the “SEC”) for resale pursuant to the Securities Act of 1933, as amended; and

     WHEREAS, as of the date hereof, the Company has not registered the Old Shares for resale under the Securities Act; and

     WHEREAS, certain disputes have arisen among the Company and the Investors regarding such failure and certain other matters; and

     WHEREAS, the parties hereto believe it is in their respective best interest to settle such disputes as provided herein.

     NOW, THEREFORE, in consideration of the mutual covenants contained herein, and intending to be legally bound, the parties hereto agree as follows:

     Section 1. Exchange. At the Closing (as defined below), the Company shall exchange each Old Share owned by an Investor for 1.125 shares (“Shares”) of the Company’s Series A Convertible Redeemable Preferred Stock, par value $0.01 per share (the “Preferred Stock”), such Preferred Stock to have the relative rights, preferences and designations set forth in Exhibit A attached hereto (the “Certificate of Designations”). In accordance with the terms of the Certificate of Designations, the Preferred Stock shall be convertible into or otherwise exchangeable for Common Stock of the Company to the extent specified therein.

     Section 2. Registration Rights.

     (a) Effective at the Closing, the Registration Rights Agreement shall be amended as follows:

          (i) Section 1 shall be amended to include the following definitions:

               “‘Exchange and Settlement Agreement’ means the Exchange and Settlement Agreement, dated as of December 27, 2007), among the Company and the Investors.”

               “‘Preferred Stock’ means the Series A Convertible Redeemable Preferred Stock, par value $0.01 per share, issued pursuant to the terms of the Exchange and Settlement Agreement.”

          (ii) The definition of “Shares” shall be amended to read as follows:

               “‘Shares’ shall mean the shares of Common Stock then issuable (without satisfaction of any conditions to issuance) pursuant to the conversion of the Preferred Stock or otherwise issued in respect of the Preferred Stock or any security issued in respect of the Preferred Stock.”

          (iii) The first sentence of Section 2(a)(i) shall be amended to read as follows:

               “The Company shall prepare and file with the SEC a Registration Statement covering all shares of Common Stock then constituting Registrable Securities for a secondary or resale offering made on a continuous basis pursuant to Rule 415 promptly after the date (“SEC Report Compliance Date”) that the Company becomes fully current in its obligations with respect to filings with the SEC, including its 2006
Form 10-K, its 2006 Form 10-Qs and the reports on Form 8-K (and amendments thereto) required to include financial statements and pro formas for the division of Wireless Facilities, Inc. (WFI) purchased by the Company in June 2007. The Company agrees to continue to use reasonable best efforts to become fully current in its filing obligations, provided that the Parties agree that the Company shall not be liable to the Investors for any delays with respect to such filings. In the event that additional shares of Common Stock constitute Registrable Securities after such registration statement is filed, the Company shall either amend such Registration Statement on a pre-effective basis, or if it has already become effective, shall prepare and file with the SEC one or more additional Registration Statements covering such additional shares of Common Stock for a secondary or resale offering made on a continuous basis pursuant to Rule 415.”

          (iv) Section 2(a)(iii) shall be deleted in its entirety.

          (v) Section 2(c) shall be amended to read in its entirety as follows:

               “The Company shall use reasonable best efforts to have the Registration Statement (and any subsequent Registration Statements) declared effective as promptly as practicable after the filing of the Registration Statement, provided that the Parties agree that the Company shall not be liable to the Investors for any delays with respect to such effectiveness. Without limiting the generality of the foregoing, the Company shall respond to any SEC comments on the Registration Statement within 15 business days of the Company’s receipt thereof. The Company shall notify the Investors by facsimile or e-mail within one business day after the Company has been advised that the Registration Statement has been declared effective and shall simultaneously provide the Investors with copies of any related Prospectus to be used in connection with the sale or other disposition of the securities covered thereby.”

          (vi) All instances of non-compliance with Section 3(o) and 3(p)(ii) occurring prior to the SEC Reports Compliance Date resulting from the Company not being fully current in its obligations with respect to filings with the SEC are hereby waived.

     (b) Except as expressly modified hereby, the Registration Rights Agreement shall remain in full force and effect.

     (c) In the event that the Company determines to file any registration statement for an offering of its equity securities on its own behalf or on behalf of one or more selling stockholders (other than a registration statement filed on Form S-4, Form S-8 or on Form S-3, in the case of a dividend reinvestment plan), the Company shall include the Registrable Securities in such registration statement (a “Piggy-back Registration Statement”) unless the Registrable Securities have been included in a Registration Statement pursuant to the terms of this Agreement and the Company is using commercially reasonable efforts to cause such Registration Statement effective. Subject to the rights of any third parties, the Company shall have right to determine in its sole discretion whether to withdraw or seek the effectiveness of any Piggy-back Registration Statement.

     Section 3. Releases. Effective as of the Closing Date, each of the Investors, on their own behalf and on behalf of their respective partners, stockholders, members, managers, investment advisers, directors, officers, employees, agents and representatives, and any and all persons or entities claiming by or through any of them (the “Investor Parties”), hereby release and forever discharge the Company and its affiliates, parents, subsidiaries, predecessors, successors, assigns, legal representatives (collectively, the “Company Released Persons”) of and from any and all manner of actions, causes of action, suits, account reckonings, covenants, agreements, damages, judgments, claims and demands whatsoever, at law or in equity, whether known or unknown, contingent or matured, and whether currently existing or hereafter arising, which the Investor Parties ever had, now have or may hereafter have (collectively, “Claims”) against the Company Released Persons arising on or prior to the Closing Date, other than any Claims arising as a result of any failure by the Company to comply with this Agreement. This release shall include, without limitation, any and all Claims (i) to the extent arising from failures of the Company to file registration statements or other filings with the SEC in a timely manner prior to the SEC Reports Compliance Date, or (ii) relating to the acquisition of the Old Shares by the Investors to the extent arising from violations of Section 10(b) of the Exchange Act and Rule 10b-5 thereunder by any Company Released Person, whether or not known to the Investor Parties on the date hereof not based on the public filings of the Company. This release shall not cover any Claims any of the Investor Parties may have against any of the Company Released Persons (x) under this Agreement or (y) arising from any violations of Section 10(b) of the Exchange Act and Rule 10b-5 thereunder by any Company Released Person, to the extent not covered by clause (ii) of the immediately preceding sentence. None of the Investor Parties shall institute any action, claim or complaint of whatever kind or nature in any federal, state or local court or other governmental agency or administrative tribunal relating to any Claim which has been released hereby or any contract, agreement, understanding or arrangement that has been canceled hereby.

     (a) It is duly organized, validly existing and in good standing under the laws of its jurisdiction of formation and has full power and authority to execute and deliver this Agreement and to perform its obligations hereunder, all of which have been duly authorized by all requisite corporate, partnership or limited liability company action, as applicable.

     (b) Neither the execution and delivery of this Agreement nor the performance by it of its obligations hereunder and thereunder will (i) contravene any provision contained in its organizational documents, (ii) violate or result in a breach (with or without the lapse of time, the giving of notice or both) of or constitute a default under (A) any material contract, agreement, commitment, indenture, mortgage, lease, pledge, note, license, permit or other instrument or obligation or (B) any judgment, order, decree, law, rule or regulation or other restriction of any governmental authority, in each case to which it is a party or by which it is bound or to which any of its assets or properties are subject, or (iii) result in the creation or imposition of any material Encumbrances on the Old Shares held by it.

     (c) No notice to, filing with, or authorization, registration, consent or approval of any governmental authority or other person is necessary for the execution, delivery or performance of this Agreement or the consummation of the transactions contemplated hereby or thereby by it.

There are no voting trust arrangements, shareholder agreements or other agreements granting any option, warrant, proxy or right of first refusal with respect to the Old Shares held by it to any person or entity. It has the absolute and unrestricted right, power and capacity to sell the Old Shares as contemplated hereby free and clear of any Encumbrances (except for restrictions imposed generally by applicable securities laws).

     (e) Its representations and warranties contained in Article 5 of the Purchase Agreement (which related to the Old Shares) are also true and correct in all material respects as of the date hereof with respect to the Shares, the PIK Shares and any Common Stock issuable upon conversion of the Shares or PIK Shares.

          (i) The representations and warranties made by the Company in Section 4 hereof qualified as to materiality shall be true and correct at all times prior to and on the Closing Date, except to the extent any such representation or warranty expressly speaks as of an earlier date, in which case such representation or warranty shall be true and correct as of such earlier date, and, the representations and warranties made by the Company in Section 4 hereof not qualified as to materiality shall be true and correct in all material respects at all times prior to and on the Closing Date, except to the extent any such representation or warranty expressly speaks as of an earlier date, in which case such representation or warranty shall be true and correct in all material respects as of such earlier date. The Company shall have performed in all material respects all obligations and covenants herein required to be performed by it on or prior to the Closing Date.

          (ii) The Company shall have obtained any and all consents, permits, approvals, registrations and waivers necessary or appropriate for consummation of the transactions contemplated by this Agreement, all of which shall be in full force and effect; provided, however, that this condition shall not require the receipt of any approvals of stockholders which may be contemplated by the Certificate of Designations (including for conversion of shares beyond permitted limits).

     Section 9. Equitable Remedies. Each of the parties hereto acknowledges that the other parties hereto would suffer immediate and irreparable harm for which an adequate remedy would not be available at law as a result of any breach of this Agreement. Accordingly, in the event of any breach, or threatened breach, of the provisions of this Agreement, each party hereto shall be entitled to an order of specific performance or other injunctive relief against the breaching party in addition to any other rights and remedies to which they may be entitled, whether at law or in equity, and each party hereby irrevocably and unconditionally consents to the entry of an order providing such relief in the event of any breach or threatened breach of the terms hereof by such party. No party shall be required to post any bond or other security in connection with any such action for specific performance or other injunctive relief.

     Section 10. Prohibited Transactions. While the Shares are outstanding, and until they have been converted into Common Stock under the Certificate of Designations, no Investor nor any Trading Affiliate (as defined in the Purchase Agreement) of such Investor, shall, and no Investor shall seek to cause any other person or entity to, directly or indirectly, effect or agree to effect any short sale, whether or not against the box, established any “put equivalent position” (as defined in Rule 16a-1(h) under the 1934 Act) with respect to the Common Stock, borrowed or pre-borrowed any shares of Common Stock, granted any other right (including, without limitation, any put or call option) with respect to the Common Stock or with respect to any security that includes, relates to or derived any significant part of its value from the Common Stock or otherwise sought to hedge its position in the Securities (each, a “Prohibited Transaction”); provided, however, that after the earlier of (i) the six-month anniversary of the SEC Report Compliance Date and (ii) the consummation of a Qualified Financing, the provisions of this Section 10 shall only apply during any period in which the Company has advised the Investors that the Company is actively seeking to complete a Qualified Financing.

This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of New York without regard to the choice of law principles thereof. Each of the parties hereto irrevocably submits to the exclusive jurisdiction of the courts of the State of New York located in New York County and the United States District Court for the Southern District of New York for the purpose of any suit, action, proceeding or judgment relating to or arising out of this Agreement and the transactions contemplated hereby.

The obligations of each Investor hereunder are several and not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the performance of the obligations of any other Investor hereunder. Nothing contained herein, and no action taken by any Investor pursuant thereto, shall be deemed to constitute the Investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated hereby. Each Investor acknowledges that no other Investor has acted as agent for such Investor in connection herewith and that no Investor will be acting as agent of such Investor in connection with monitoring its investment in the Company or enforcing its rights hereunder.
